Abstract
The mode transforming structure includes a first waveguide structure. A slot waveguide region is coupled to the first waveguide structure. The slot waveguide region includes one or more complementary tapered pairs so near lossless transforming between the first waveguide structure and the slot waveguide region occurs so as to allow optical modes to be transferred between the first waveguide and the slot waveguide region.
